MailKit
MailKit is a cross-platform .NET email protocol library used to implement IMAP, POP3, and SMTP functionality. It provides specialized client libraries for managing remote mailboxes, retrieving and downloading messages, and composing and transmitting emails to remote servers.
The library supports secure identity verification through SASL authentication and OAuth 2.0 token-based flows. It includes capabilities for routing traffic through proxy gateways and decrypting PGP-encrypted content embedded within email bodies.
The project covers a broad range of email operations, including folder management, server-side message searching, and the synchronization of folder caches. It provides tools for message composition—such as generating replies and forwards—alongside utilities for parsing MIME structures, extracting attachments, and processing read receipts.
Protocol communication logging is available for recording client and server interactions to a file or output stream.
Features
- Email Clients - Provides a comprehensive .NET library for building cross-platform applications that implement email client functionality.
- Email Protocol Libraries - Serves as a comprehensive cross-platform .NET library for IMAP, POP3, and SMTP protocol implementation.
- SMTP Clients - Implements a client library for composing and transmitting email messages to remote SMTP servers.
- Protocol Abstraction Layers - Provides architectural layers that standardize IMAP, POP3, and SMTP into a consistent internal API.
- Email Header Parsers - Extracts metadata and routing information by scanning and tokenizing the initial block of an email message stream.
- Email Transmission Services - Transmits email messages to recipients using the SMTP protocol with secure encryption and authentication.
- IMAP Client Integrations - Provides capabilities to manage email folders, search messages, and update flags via IMAP integrations.
- POP3 Email Retrieval - Implements the POP3 protocol for downloading email messages from servers with support for encryption.
- Secure Socket Wrappers - Manages raw TCP connections with integrated security layers for TLS-encrypted communication.
- Stream-Based Email Parsers - Processes email data from input streams to handle large attachments without loading the entire message into memory.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
